'1 Claim. (Cl. 20-52) This invention relates to a split jamb windowunit.

An object of the invention is to facilitate the installation of windowunits by providing a split jamb unit capable of adjusting to suitvarious window openings. My window unit is made in two sections, theoutside is first installed with the weather stripping and then theinside is made and they are put together to form a complete window unit.

It now requires 30 to 45 minutes to install and trim out one window. Mywindow unit can be installed in about three minutes. The great advantageof a window unit constructed in accordance with my invention is that itwill adjust to any size wall. Where there are different jamb sizes mywindow unit will open to take care of the wall. The necessary advantagesflowing from the invention are the saving of time, effort, money,millwork, paper work, etc.

Another object of the invention is to provide a split jamb window unitwhich is capable of being constructed as a single window, a doublewindow, a triple window or any multiple window, it making no differencewhether the window is a two light or more. Moreover, the principles ofmy invention can be practiced not only with wooden windows but withmetal windows with practically equal facility.

Other objects and features of importance will become apparent infollowing the description of the illustrated form of the invention.

Figure 1 is a perspective view of a window constructed in accordancewith the invention.

Figure 2 is a sectional view taken on the Figure 1.

Figure 3 is a transverse sectional view of the window in Figure 1.

Figure 4 is an exploded perspective view of the split jamb of the windowof Figure 1.

Figure 5 is a fragmentary sectional view showing the mullion, partingstrip and other structure that will be used in a double, triple or othermultiple window.

In the accompanying drawings there is a window which is constructed insuch a manner as to exemplify the principles of the invention. Thewindow is of the double hung sliding sash type and has an upper andlower window sash 12 and 14 respectively which may use sash weight orwhat is now more common, spring torsion brakes 16 on opposite sides ofthe window members. Window 10 is set beneath header 20 and has a headercornice 22 nailed to it beneath the drip cap 24. Side casing 26 hasmembers 28 and 30 on opposite sides of the window opening and above thesill 32. Head blind stop 34 is located behind the side casing and headercornice while the side blind stops 38 and 40 are behind the side casings28 and 30. Weatherstrip 42 is behind the side blind stops and is nailedor otherwise secured to the window jamb.

The two outside window jambs sides 46 and 48 are constructed the same.Each has a smooth inner surface and a notch 49 and 50 respectively onthe outer surfaces line 22 of thereof. The outside head jamb 52 isformed with a smooth inner surface and an elongate notch '54 on theouter surface. The inside jamb is constructed of two jamb sides '56 and58 which are constructed with smooth outer surfaces and notches 60 and62 on the inside surfaces thereof. The inside head jamb 64 isconstructed with a smooth outside surface and an elongate notch 66 onthe inside surface. The notches 66 and 54 are interiitted (Figure 2) andthe notches of the inside jamb sides and the notches of the outside jambsides are interfitted (Figure 3). Accordingly, the inside jamb and theoutside jamb may be adjusted with respect to each other in order tocompensate for different thicknesses of walls within which the windowunit is to be assembled.

The window is trimmed out on the inside by an inside head casing 70 anda pair of inside casing sides 72 and '74 that terminate on the stool 76.Apron 78 is below the stool and attached in the customary way. Theinside casing is located in front of the window rails 78 and 80.

As shown in Figure 3 the principles of the invention are applicable todouble windows. The same would hold true for other multiples of windowsin that the structure shown in Figure 5 would merely be duplicated.Here, the mullion 82 is mounted over the adjacent side blind stops 84and 86, while a facia strip 88 is at the front of the multiple window.The side jambs 90 and 92 are each made in two pieces and are adjustablewith respect to each other in a manner identical to that shown anddescribed in connection with window unit 10. Therefore, the entiremultiple window of Figure 5 is adjustable to compensate for differencesin wall thickness just as the window unit 10.

The foregoing is considered as illustrative only of the principles ofthe invention. Further, since numerous modifications and changes willreadily occur to those skilled in the art, it is not desired to limitthe invention to the exact construction and operation shown anddescribed, and accordingly, all suitable modifications and equivalentsmay be restored to, falling within the scope of the invention asclaimed.

What is claimed as new is as follows:

An adjustable window unit comprising an inside casing, an outsidecasing, a pair of window members movable to the window open and windowclosed positions and located between said inside and outside casings,inside jambs and outside jambs, said inside and outside jambs havingsides and head jamb members, and means interfitting said inside jambmembers and outside jamb members and said inside jamb sides and saidoutside jamb sides with each other so that they are adjustable in orderto compensate for different thicknesses of walls, weatherstripping forboth window members permanently attached only to the outside side jambsin sealing engagement therewith so that the inside side jambs may beadjusted without adjusting the Weatherstripping, and the window membersmovable in said Weatherstripping.
